What if we decide that the Amazon rainforest has a negative WAW sign? Would you be in favor of completely replacing it with a parking lot, if doing so could be done without undue suffering of the animals that already exist there?
Definitely not completely replacing because biodiversity has diminishing returns to land. If we pave the whole Amazon we’ll probably extinct entire families (not to mention we probably cause ecological crises elsewhere and disrupt ecosystem services etc), whereas on the margin we’ll only extinct species endemic to the deforested regions.
If the research on WAW comes out super negative I could imagine it being OK to replace half the Amazon with higher-welfare ecosystems now, and work on replacing the rest when some crazy AI tech allows all changes to be fully reversible. But the moral parliament would probably still not be happy about this. Eg killing is probably bad, and there is no feasible way to destroy half the Amazon in the near term without killing most of the animals in it.
